Qiskit Machine Learning 0.9.0 has not been released. Its still work in progress and does not support Qiskit 2.0 either. Qiskit 0.44 is too old. The requirements need >1.0 see https://github.com/qiskit-community/qiskit-machine-learning/blob/0a114922a93b6b8921529ada886fe9be08f163b2/requirements.txt#L1 for this (that's on the 0.8 branch and on main its been pinned to <2.0 as well at present). Try installing the latest version prior to 2.0 i.e Qiskit 1.4.2 which should have things working for you.
